Post From: Some ticks seem wrongly stamped Bid or Ask volume

Hi, I'm investigating why my NT8 orderflow has different Delta readings than Sierra. They both use Rithmic, there should be no difference. They both generally match, but still, sometimes, there's a difference on some ticks, leading to differences in overall delta. After investigation, it looks like some ticks on Sierra seem wrongly stamped as bid/ask. Example here 15:02:52 on the DAX, GMT+1 time. We have 2 ticks during this second, they both happen at the bid, but the second one is marked 'Ask Volume'. |
